Condition monitoring of power lines is beneficial to improve the reliability of power grid operation. Optical fiber sensing has advantages such as long sensing distance, distributed measuring and electric passivity, which is developed rapidly in the field of power line monitoring. In order to speed up the development of optical fiber condition monitoring technology for transmission lines, this paper systematically reviews a variety of different condition monitoring technologies for optical fiber transmission lines,and puts forward the key points and ideas of future research. Firstly, the measuring principles of fiber Bragg grating sensing, distributed optical fiber sensing and optical fiber interferometric sensing are introduced, and advantages,disadvantages and applicable conditions of different optical fiber sensing technologies are compared. Secondly, the advances of optical fiber sensors in the field of overhead transmission lines and high-voltage cable condition monitoring are focused on, and the outlines of research context and measurement effect of the existing research on the static, low frequency and high frequency state perception are illustrated. Then, combined with the demand of transmission line operation condition monitoring, the difficulties in the existing technology are analyzed. Finally, the research priorities and the future developments are proposed. It is expected to provide a reference for the digital transformation and development of transmission lines.
